Abstract
In this paper, we discuss the software performability evaluation considering the real-time property; this is defined as the attribute that the system can complete the task within the stipulated response time limit. The dynamic software reliability growth process is described by the nonhomogeneous Poisson process (NHPP). Assuming that the software system can process multiple tasks simultaneously and that the arrival process of the tasks also follows an NHPP, we analyze the distribution of the number of tasks whose processes can be completed within the processing time limit with the infinite-server queuing model. We derive several software performability measures considering the real-time property. Finally, we illustrate several numerical examples of the measures and discuss the software performability analysis.
